Psychosocial Correlates and Outcomes of Yoga or Walking Among Older Adults

Few researchers have compared psychological correlates and outcomes of yoga with more traditional forms of exercise. The authors' primary aim was to compare changes in the psychosocial outcomes of mood and state anxiety produced by an acute bout of yoga or walking among older adults. The secondary aim was to compare selected psychosocial correlates of activity. Participants were 51 adults who were 50 years of age or older who walked for exercise or participated in a yoga class. Results revealed that yoga participants had significantly greater levels of depression and perceived barriers to exercise, and lower quality of life than did walkers. With control for these differences, yoga practitioners had improved levels of fatigue pre- to postsession, compared with walkers. With control for differences in demographic variables, these changes were no longer significant. It is possible that yoga practitioners seek out mindful-based exercise to cope with greater levels of depression and lower levels of quality of life.     

The Dynamics of Visual Reweighting in Healthy and Fall-Prone Older Adults

Multisensory reweighting (MSR) is an adaptive process that prioritizes the visual, vestibular, and somatosensory inputs to provide the most reliable information for postural stability when environmental conditions change. This process is thought to degrade with increasing age and to be particularly deficient in fall-prone versus healthy older adults. In the present study, the authors investigate the dynamics of sensory reweighting, which is not well-understood at any age. Postural sway of young, healthy, and fall-prone older adults was measured in response to large changes in the visual motion stimulus amplitude within a trial. Absolute levels of gain, and the rate of adaptive gain change were examined when visual stimulus amplitude changed from high to low and from low to high. Compared with young adults, gains in both older adult groups were higher when the stimulus amplitude was high. Gains in the fall-prone elderly were higher than both other groups when the stimulus amplitude was low. Both older groups demonstrated slowed sensory reweighting over prolonged time periods when the stimulus amplitude was high. The combination of higher vision gains and slower down weighting in older adults suggest deficits that may contribute to postural instability.     

Disposable Time and Disposable Income: Problem Casino Gambling Behavior in Older Adults

Increasing numbers of retirees spend their leisure time in the ever-growing number of gambling casinos in this country. For most older adults, casino gambling is a new form of excitement and entertainment. However, for some retirees, especially those vulnerable to depression from the changes and losses that can occur in aging, casino gambling can become disordered, problematic, and/or an addiction. Although prevalence studies have examined the incidence of problem gambling in other age groups, little attention has been directed to the impact of casino gambling on older adults. The authors discuss problem and pathological gambling in retired older adults, and provide clinical case examples of a growing number of older adults with problem gambling behaviors seen in an outpatient geriatric psychiatry clinic. Finally, they urge that an evaluation of gambling behaviors be a routine portion of geriatric clinical evaluations.     

The Impact of Spirituality on Wellness for Appalachian Older Adults

The authors examined the role spirituality can play as a protective factor in the wellness of older adults residing in the Appalachian region of the United States. Analysis of participants' interviews identified 4 themes. These themes and implications for counselors working with Appalachian older adults are discussed.     

Practical Memory Concerns of Older Adults

We examine practical memory concerns in a sample of community-dwelling older adults. Participants responded to open-ended questions that were designed to solicit information regarding memory self-efficacy, memory management, memory remediation, and fears about memory aging in adulthood. Results indicated that (a) important dates, such as birthdays and anniversaries, were easily remembered, but names were not; (b) external memory aids were used most frequently; (c) a desire to improve memory for names and certain types of verbal information was expressed; and (d) loss of independence emerged as a fear associated with memory aging. Implications of these findings for the design of strategies to improve everyday memory performance and clinical memory management in older adults are discussed.     

老年人错误记忆的情绪效价和时间效应

基于信号检测论的框架, 考察不同的情绪效价以及时间间隔如何交互影响老年人在图片再认任务中的辨别力(d′)和判断标准(β), 进而影响其错误记忆。以21名老年人(女性14名)为被试, 平均年龄67.17 ± 5.03岁。根据中国老年人对国际情绪图片库(International Affective Picture System, IAPS)中图片评定的情绪参数, 选出积极、消极和中性图片各60张作为学习材料。另选积极、消极和中性图片各30张作为每次再认测验的干扰材料, 并且两次再认测验的干扰材料不同。短时间隔条件让老年人在图片记忆编码半个小时后完成对图片的再认测验; 长时间隔条件则为在三周后完成对图片的再认测验。结果发现: 1)在短时间隔条件下, β和d′共同影响虚报率; 而在长时间隔条件下, 只有β影响虚报率, d′不影响虚报率; 2)无论是在短时还是长时间隔条件下, 积极图片与消极图片的判别力d′都没有显著差别; 3)在短时间隔条件下, 老年人对消极图片的β更低、虚报率更高; 在长时间隔条件下, 老年人对积极图片的β更低、虚报率更高。研究结果表明: 老年人的错误记忆受判别力d′和判断标准β的影响。情绪效价通过作用于老年人的反应倾向(判断标准β)、而非记忆质量(判别力d′)来影响其错误记忆。时间间隔可以调节情绪效价对老年人判断标准β和错误记忆的作用, 使之随时间发生反转。老年人的“积极效应”在错误记忆中可能表现为随着时间的流逝, 老年人更愿意将积极信息报告为经历或学习过的信息。     

The Relationship between Everyday Problem Solving and Inconsistency in Reaction Time in Older Adults

ABSTRACT

The purpose of the present study was to investigate whether inconsistency in reaction time (RT) is predictive of older adults' ability to solve everyday problems. A sample of 304 community dwelling non-demented older adults, ranging in age from 62 to 92, completed a measure of everyday problem solving, the Everyday Problems Test (EPT). Inconsistency in latencies across trials was assessed on four RT tasks. Performance on the EPT was found to vary according to age and cognitive status. Both mean latencies and inconsistency were significantly associated with EPT performance, such that slower and more inconsistent RTs were associated with poorer everyday problem solving abilities. Even after accounting for age, education, and mean level of performance, inconsistency in reaction time continued to account for a significant proportion of the variance in EPT scores. These findings suggest that indicators of inconsistency in RT may be of functional relevance.     

Absence of Ankle Stiffening While Standing in Focus and Cognitive Task Conditions in Older Adults

Abstract

Research suggests that an external focus or cognitive task may improve postural control. Removing attention from movement production may promote automaticity, or the tasks may promote ankle stiffening. To investigate these two theories, twenty older adults stood while performing baseline standing, internal focus, external focus, and two cognitive tasks. Changes in postural control occurred in external focus and cognitive task conditions compared to baseline and internal focus, while no change occurred in cocontraction indices. This suggests that an external focus and cognitive task can improve postural control in older adults. Since no change occurred in cocontraction indices across conditions, this suggests that stiffening cannot explain these changes. Instead, changes could be due to automaticity of sway.     

Counseling Older Adults with Dementia: A Survey of Therapists in Massachusetts

Although much has been written about therapeutic interventions with caregivers, little is known about the counseling services that are available for victims of dementia. The present study was designed to explore community mental health center (CMHC) services and therapists' experiences in providing psychotherapy to this population in Massachusetts. Only 27 of the 36 CMHCs in the state reported providing mental health services to older adults with a dementing illness. A survey of therapists who specialized in working with older adults found that the percentage of older adult clients estimated to have dementia averaged about half of their caseload. Older persons in the early phase of a dementing illness were most frequently referred for depression and anxiety, whereas those with moderate decline were most frequently referred for management of disruptive behavior. The most common services provided to clients with dementia consisted of assessment and individual counseling. The latter finding indicates a discrepancy between what is practiced and the professional literature. Most of the psychotherapy described in the literature concerns group interventions, which were rarely provided by the mental health centers in Massachusetts. The centers tended to offer individual counseling; however, little information on how to provide this form of treatment can be found.

Comparison of Privacy Consciousness Between Younger and Older Adults

The degree of being conscious about privacy for the self and others is known as privacy consciousness. This study aimed to compare privacy consciousness between younger and older adults. Japanese younger (n = 166) and older (n = 145) adults were requested to rate all items in the Privacy Consciousness Scale, which assessed their degree of consciousness about privacy for the self and others and behaviors for maintaining privacy based on this consciousness. Results indicated that older adults scored lower on Consciousness Regarding Privacy of Others and higher on Behaviors Regarding Privacy of Others than younger adults. However, no significant difference was found in Consciousness and Behaviors Regarding Privacy of the Self between younger and older adults.     

When Psychologists Work with Older Adults: A Survey of Ethical Beliefs and Practices

Despite the number of publications concerning legal and ethical issues faced by psychologists, and despite the increased interest in addressing specific concerns related to aging, little is known about the actual beliefs and practices of psychologists when they work with older adults. Given the changing demographics in the United States, many mental health professionals will have contact with older adult clients, and the focus of the present study was to examine the extent to which psychologists are prepared to work competently with older adult clients. Survey data were collected from 156 APA Division 12 (Clinical Psychology) and 17 (Counseling Psychology) members regarding the degree to which they engaged in each of 50 behaviors and the degree to which they considered each behavior ethical. Findings are presented in terms of percentages of responses to items on the questionnaire, and ANOVAs were performed on important demographic items to identify statistically significant differences among variables. Coursework in geropsychology or aging, specialization with older adults, and working with a high percentage of older adults were related to higher scores on the Overall Ethical Behavior scale. Females scored higher than males on the Overall Ethical Belief scale.

Perceptions of Responsibility and Mental Health Help-Seeking Among Psychologically Distressed Older Adults

This study explored the perceptions of responsibility for the cause and the solution of problems and the models of helping (or helping orientations) characterizing a sample of 319 community-dwelling, psychologically distressed older adults. All participants were referred for psychotherapy and had either accepted or rejected their referrals. We investigated whether the models distinguished acceptors and rejecters of psychotherapy referrals and whether they were differentially associated with help-seeking from nontherapist helpers. Results indicated that the preponderance of respondents subscribed to the moral and compensatory models. The compensatory model was associated with rejection of referrals, whereas the moral model was associated with increased help-seeking both from mental health professionals and from other formal and informal helpers. Implications of the findings for promoting older adults' utilization of mental health services are discussed.     

Useful Field of View and Other Neurocognitive Indicators of Crash Risk in Older Adults

Older adults represent a rapidly growing segment of the driving population. Although most older drivers are safe, research has shown that this group has more crashes per mile driven than most other age groups. The purpose of the present investigation was to examine the utility of a set of commonly used neuropsychological/cognitive tests in comparison to a newer measure of visual attention (Useful Field of View; UFOV®) in predicting state-recorded, at-fault crashes over the previous five years in a group of older adult drivers. Participants (N = 239) completed tests of mental status, visual attention, memory, and UFOV®. Results show that among all cognitive tests administered, UFOV® was most strongly related to crash involvement, with high levels of sensitivity (86.3%) and specificity (84.3%) at the standard cutoff score of 40% reduction. Practical implications for the assessment of crash risk are discussed.     

Review of Social Cognition Research on Stereotyping: Application to Psychologists Working with Older Adults

This paper summarizes a number of cognitive processes that contribute to the formation and maintenance of stereotypes. Specific discussion centers on how these may play a role in shaping perceptions of older adults. Suggestions are offered as to how psychologists might combat their tendency to stereotype because older adults have special needs that must be identified to provide accurate case conceptualization and effective psychotherapy from a professional ethics perspective.

老年执行功能的认知可塑性和神经可塑性

执行衰退假说认为执行功能的特异性衰退是引起认知年老化的主要原因, 近年来越来越多的研究表明, 老年人的执行功能及其相关脑区(主要为前额叶)存在可塑性, 通过训练执行功能的衰退可得到缓解, 且相关脑区的激活水平、脑容量或神经递质都可发生改变; 部分研究还发现执行功能训练对其它认知能力有一定的迁移效应。这些发现对于认知年老化理论的继续探索和认知干预研究的实践应用都具有重要意义。
